1 Claim. (01. 221-61) My invention relates in general to receptacles The bottom wall 5 is apertured being provided for dispensing powder which by reason of its with one or more openings of relatively small size, nature and use requires a modicum of the recephere shown by preference as a single opening 8, tacle content. the shape of which may be varied, but is shown 5 In particular, it concerns such dispensing repreferably, as seen in Fig. 3, of semi-circular or 5 ceptacles as are adapted for hand use, the dishalf-moon contour. The outer diameter of the charge of the fluent solid being controlled by one sleeve is substantially the same as the inner dior more relatively small or contracted apertures. ameter of the bottle neck and the length of Such receptacles, for example, are hand shakers the sleeve is proportioned to that of the neck for various powders, salt, pepper, talcum, tooth throat, so that when said sleeve is slipped down 10 powder, insect powder, and many other fluent into the neck to a frictionally tight fit with its solids. flange 1 resting upon the top of the neck and Though my invention is not essentially conlimiting its insertion, said sleeve by reason of its fined to glass containers, still, for several reasons apertured bottom wall 5, presents in the bottlewhich I shall hereinafter set forth, it is structhroat a diaphragm control well down within 15 turally adapted for glass bottles, in which conthe neck, and restricting by its opening 8, the flow nection it is my present opinion that its best use of the powder to the proper modicum when the lies. bottle is tipped.

For use of '20 out impairment of their customary neat and atthe powder, the screw-cap 9 is removed.

I claim:--

A powder-dispenser comprising in combination a glass-bottle having an extemally-threaded neck with a full-open throat; a metal sleeve in said throat of a length proportioned to that of the neck-throat and of a diameter adapting it for readily insertable and removable frictional contact throughout its length with the throat wall, said sleeve having a full-open top with a penetration-limiting flange resting on the top of the neck and a partially open, relatively stiff bottom-wall of less discharge capacity than the full-open top; and a flat-top screw-cap fitted upon the neck of the bottle to lie closely upon and cover the full-open top of the sleeve.
